With the reduction in vehicles powered by fossil fuels, lithium ion batteries have become more prevalent, with many automobile manufacturers pushing to produce highly efficient electric vehicles. This has pushed the production of lithium to the forefront of peoples' minds; however, another component of these batteries is just as vital. Carbonaceous materials have always been the most important aspect of the anode of rechargeable lithium ion batteries, because of their higher specific charges and lower redox potentials than other candidate materials. Graphite is the most common anode material, and as such should not be neglected. In addition to batteries, graphite is used in brake linings, lubricants, powdered metals, refractory applications, and steelmaking. This Collaborative Research and Development (CRD) Grant proposal aims at generating new knowledge related to processing of graphite from its ores, and the purification through sustainable aqueous processing routes. It is in collaboration with SRG Graphite, to be undertaken in the Department of Mining and Materials Engineering at McGill University. This project will be headed by Prof Kristian Waters and Prof Sidney Omelon, and will encompass mineral processing and aqueous processing routes to produce a high-grade concentrate to be used in different applications, including battery anodes. SRG Graphite will be active in all aspects of this collaborative research project, which will place Canadian companies at the forefront of this growing market, and enable the sustainable development of a mineral resource that has important economic value to Canada.

随着化石燃料供电的车辆减少，锂离子电池变得越来越普遍，许多汽车制造商都在推动生产高效的电动汽车。 这将锂的生产推向了人们思想的最前沿。但是，这些电池的另一个组成部分同样重要。 与其他候选材料相比，碳质材料一直是可充电锂离子电池阳极的最重要方面，因为它们具有更高的特异性电荷和较低的氧化还原电位。 石墨是最常见的阳极材料，因此不应忽略。 除了电池外，石墨还用于制动衬里，润滑剂，粉末状金属，难治性应用和钢制造。 这项合作研究与发展（CRD）赠款提案旨在产生与石墨从其矿石中处理以及通过可持续水分加工途径进行纯化有关的新知识。 它与SRG石墨合作，将在麦吉尔大学采矿和材料工程系进行。 该项目将由克里斯蒂亚水教授和西德尼煎蛋教授领导，并将涵盖矿物加工和水加工路线，以生产高级浓缩物，以用于不同应用，包括电池阳极。 SRG石墨将活跃于该协作研究项目的各个方面，该项目将使加拿大公司处于这个不断增长的市场的最前沿，并使可持续发展的矿产资源的可持续发展对加拿大具有重要的经济价值。
